Many thanks to all those who have contributed to this thread -
particularly Anthony van E, Ivor P, Karl H, Richard H, Fred F and Nigel
C. I will try getting one of my Peltors converted and then comment.
It is interesting that one of you commented that after converting a DC,
there was "tappet like" noise; that is exactly the problem with the
BOSE.
Fred - yes, I do have baluns fitted.
Ivor - it is my understanding that, as far as the London FIR frequencies
are concerned, it is only the FIR controllers' output that is
rebroadcast, and not the incoming aircrafts' transmissions. Correct me
if I am wrong!
It looks like Lightspeed off the shelf, or converted Peltors to me!
